しかしながら、上記従来の内視鏡システムを構成する操作装置においては、把持部を掴む手指により操作レバーを把持部から離間する方向に揺動させた際に、手指が伸びきった状態となってしまうため、操作レバーの操作性が悪いという問題がある。
この発明は上述した事情に鑑みてなされたものであって、操作レバーの操作性を向上できる内視鏡用操作装置及びこれを備えた内視鏡システムの提供を目的としている。 However, in the operation device constituting the conventional endoscope system described above, when the operation lever is swung in the direction away from the gripping portion by the finger gripping the gripping portion, the finger is fully extended. Therefore, there is a problem that the operability of the operation lever is poor.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide an endoscope operation device that can improve the operability of an operation lever and an endoscope system including the same.

上記目的を達成するために、この発明は、細長い管状に形成され、先端に湾曲可能な湾曲部を設けた挿入部に接続され、前記湾曲部の湾曲動作の遠隔操作を行う内視鏡用操作装置であって、前記挿入部の基端側に取り付けられる筐体と、前記筐体の一端側に設けられ、前記筐体を手により把持する把持部と、前記筐体の他端側に、前記筐体に対して揺動可能に設けられた操作レバーと、前記操作レバーの先端を前記筐体の一端側に延出させる延出手段とを備える内視鏡用操作装置を提供する。   In order to achieve the above object, the present invention provides an endoscope operation which is connected to an insertion portion which is formed in an elongated tubular shape and has a bending portion which can be bent at a distal end thereof, and which remotely controls the bending operation of the bending portion. A device that is attached to a proximal end side of the insertion portion, a grip portion that is provided on one end side of the housing and grips the housing by hand, and on the other end side of the housing, Provided is an endoscope operation device including an operation lever provided so as to be swingable with respect to the housing, and an extending means for extending a tip of the operation lever toward one end of the housing.

この発明に係る内視鏡用操作装置において、湾曲部の湾曲動作は、把持部を掴む手の指（例えば、親指）で操作レバーの先端を接触させた状態で行われる。すなわち、この状態において前述の手指を動かすことにより、筐体に対して操作レバーが傾斜し、操作レバーの傾斜方向に応じた方向に湾曲部が湾曲することになる。
ここで、筐体の他端側に操作レバーを揺動させた際には、操作レバーの先端が把持部から離間する方向に移動することになるが、延出手段によって操作レバーの先端が筐体の一端側に延出しているため、筐体の他端側に操作レバーを傾斜させた状態においても、操作レバーの先端と把持部との距離を小さくすることができる。したがって、この状態おいて操作レバーを操作する手指が伸びきることを防止できる。 In the endoscope operating device according to the present invention, the bending operation of the bending portion is performed in a state in which the tip of the operation lever is in contact with a finger (for example, a thumb) of a hand that holds the holding portion. That is, by moving the above-described fingers in this state, the operation lever is inclined with respect to the housing, and the bending portion is bent in a direction corresponding to the inclination direction of the operation lever.
Here, when the operating lever is swung to the other end side of the casing, the tip of the operating lever moves in a direction away from the gripping portion, but the tip of the operating lever is moved by the extending means. Since it extends to one end of the body, the distance between the tip of the operating lever and the grip portion can be reduced even when the operating lever is inclined to the other end of the housing. Therefore, it is possible to prevent the fingers operating the operation lever from extending in this state.

また、前記操作レバーが、前記筐体に連結された略棒状のレバー本体と、前記レバー本体の先端にノブ部材とを備え、前記延出手段が、前記ノブ部材から前記筐体の一端側に向けて突出する突出部からなる内視鏡用操作装置を提供する。
この発明に係る内視鏡用操作装置において、操作レバーを揺動させる際には、把持部を掴む手指をノブ部材に接触させる。そして、操作レバーを筐体の他端側に揺動させる場合には、把持部を掴む手指を突出部に接触させておくことにより、手指が伸びきることを確実に防止できる。 The operation lever includes a substantially rod-shaped lever main body connected to the housing, and a knob member at a tip of the lever main body, and the extending means extends from the knob member to one end of the housing. Provided is an endoscope operating device including a protruding portion protruding toward the end.
In the endoscope operating device according to the present invention, when the operating lever is swung, the finger that grips the gripping portion is brought into contact with the knob member. And when swinging an operation lever to the other end side of a housing | casing, it can prevent reliably a finger extending | stretching by making the finger which grips a holding part contact a protrusion part.

さらに、前記突出部が、前記ノブ部材と一体的に形成され、前記ノブ部材が前記レバー本体に対して着脱自在に設けられている内視鏡用操作装置を提供する。
この発明に係る内視鏡用操作装置によれば、突出部をノブ部材と一体的に形成することにより、操作レバーを構成する部品点数を増やすことなく、ノブ部材に接触する手指が伸びきることを防止できるため、内視鏡用操作装置の製造コストの増加を抑えることができる。
また、ノブ部材をレバー本体に対して着脱できるため、ノブ部材に接触させる手指の長さに応じて突出長さの異なるノブ部材を選択することができる。すなわち、例えば、ノブ部材に接触させる手指の長さが短い場合には、突出部の突出長さが長いノブ部材を選択し、同手指の長さが長い場合には、突出部の突出長さが短いノブ部材を選択すればよい。 Furthermore, the operation part for endoscopes in which the said protrusion part is integrally formed with the said knob member, and the said knob member is provided with respect to the said lever main body so that attachment or detachment is provided is provided.
According to the endoscope operating device according to the present invention, the fingers touching the knob member can be extended without increasing the number of parts constituting the operating lever by forming the protruding portion integrally with the knob member. Therefore, an increase in the manufacturing cost of the endoscope operating device can be suppressed.
Further, since the knob member can be attached to and detached from the lever body, it is possible to select knob members having different projecting lengths according to the length of the finger to be brought into contact with the knob member. That is, for example, when the length of the finger to be brought into contact with the knob member is short, a knob member having a long protrusion length is selected, and when the length of the finger is long, the protrusion length of the protrusion portion is selected. A short knob member may be selected.

また、前記突出部が、前記ノブ部材に対して着脱自在に設けられている内視鏡用操作装置を提供する。
この発明に係る内視鏡用操作装置によれば、把持部を掴む手指の長さに応じた適切な突出長さの突出部を選択してノブ部材に取り付けることができる。また、必要に応じて突出部のみを交換する構成であるため、ノブ部材２７自体の交換が不要となり、内視鏡用操作装置の製造コスト増加を抑えることができる。 In addition, the endoscope operating device is provided in which the protruding portion is provided detachably with respect to the knob member.
According to the endoscope operating device according to the present invention, it is possible to select and attach to the knob member a protrusion having an appropriate protrusion length according to the length of the finger that holds the grip. Moreover, since it is the structure which replace | exchanges only a protrusion part as needed, replacement | exchange of knob member 27 itself becomes unnecessary, and it can suppress the manufacturing cost increase of the operating device for endoscopes.

さらに、前記操作レバーが、前記筐体に連結された略棒状のレバー本体と、前記レバー本体の先端に設けられたノブ部材とを備え、前記延出手段が、前記レバー本体の中途部を前記筐体の一端側に向けて折り曲げた屈曲部からなる内視鏡用操作装置を提供する。
この発明に係る内視鏡用操作装置によれば、レバー本体の中途部に屈曲部を形成することにより、レバー本体を操作する手指に接触させるノブ部材が把持部側に確実に近づくことになる。したがって、操作レバーを筐体の他端側に揺動させても、把持部を掴む手指をノブ部材に容易に接触させることできるため、手指が伸びきることを確実に防止できる。 Further, the operation lever includes a substantially rod-shaped lever main body connected to the housing, and a knob member provided at a tip of the lever main body, and the extending means includes a middle portion of the lever main body. Provided is an endoscope operating device including a bent portion bent toward one end side of a housing.
According to the endoscope operating device of the present invention, the bent member is formed in the middle part of the lever main body, so that the knob member to be brought into contact with the finger operating the lever main body approaches the gripping part side reliably. . Therefore, even if the operating lever is swung to the other end side of the housing, the finger that grips the grip portion can be easily brought into contact with the knob member, so that the finger can be reliably prevented from extending.

また、細長い管状に形成され、先端に湾曲可能な湾曲部を設けた挿入部と、前記内視鏡用操作装置と、前記湾曲部の先端の外部を撮像する撮像手段と、前記撮像手段により撮影された画像を表示する表示部とを備える内視鏡システムを提供する。
この発明に係る内視鏡システムによれば、撮像手段により撮像された画像が表示部の画面に表示される。そして、この表示部の画面に操作レバーの傾斜方向を連動させることができるため、表示部の画面を見ながら直感的に操作レバーを操作することが可能となる。すなわち、例えば、表示画面の上側の領域を視認する場合には、操作レバーを上側に傾斜させればよい。 Further, the insertion portion is formed in an elongated tubular shape and provided with a bending portion that can be bent at the distal end, the endoscope operating device, an imaging means for imaging the outside of the distal end of the bending portion, and photographing by the imaging means. An endoscope system is provided that includes a display unit that displays a captured image.
According to the endoscope system according to the present invention, the image captured by the imaging unit is displayed on the screen of the display unit. Since the tilt direction of the operation lever can be linked to the screen of the display unit, the operation lever can be intuitively operated while viewing the screen of the display unit. That is, for example, when the upper region of the display screen is visually recognized, the operation lever may be tilted upward.

本発明の内視鏡用操作装置によれば、把持部を掴む手指により操作レバーを把持部から離間する方向に傾斜させても、手指が伸びきることを防止できるため、把持部を掴む手による操作レバーの操作性を向上できる。
また、本発明の内視鏡システムによれば、表示部の画面を見ながら直感的に操作レバーを操作することが可能となるため、体腔内や構造物の管内や隙間等の観察検査を容易に行うことができる。 According to the endoscope operating device of the present invention, even if the operating lever is tilted in the direction away from the gripping portion by the finger gripping the gripping portion, it is possible to prevent the finger from extending, so that the hand gripping the gripping portion The operability of the control lever can be improved.

The knob member 27 is provided with a protruding portion 29 that protrudes toward one end side of the housing 21, that is, toward the gripping portion 21 a, and the protruding portion 29 is formed integrally with the knob member 27. . The protruding length of the protruding portion 27 toward one end of the housing 21 is the lever body in an upright state at the midpoint of the entire length of the knob member 27 in the direction connecting the one end and the other end of the housing 21. It is equal to the length shifted to the one end side with respect to 25 axis lines L1. The projecting portion 29 constitutes an extending means for extending the distal end of the operation lever 23 to one end side of the housing 21.
Note that the protruding length of the protruding portion 29 is such that even when the lever body 25 is inclined to the other end side of the casing 21, the holding portion 21a is more than the axis L1 of the lever body 25 when the end portion of the protruding portion 29 is upright. It is preferable to set it so as to be located on the side.

以上のように構成された内視鏡システム１において、操作レバー２３のレバー本体２５を筐体２１に対して傾斜させた際の作用について以下に説明する。
直立状態にある操作レバー２３のレバー本体２５を、筐体２１の他端側に（Ｙ１方向）に傾斜させた際には、操作レバー２３のノブ部材２７が把持部２１ａから離間する方向に移動することになる。そして、ノブ部材２７の突出部２９は筐体２１の一端側に突出しているため、筐体２１の他端側に操作レバー２３のレバー本体２５が傾斜した状態においては、ノブ部材２７と把持部２１ａとの距離を小さくすることができる。したがって、この状態おいて操作レバー２３を操作する手指Ｆが伸びきることを防止できる。 In the endoscope system 1 configured as described above, an operation when the lever body 25 of the operation lever 23 is tilted with respect to the housing 21 will be described below.
When the lever body 25 of the operating lever 23 in the upright state is tilted toward the other end of the housing 21 (Y1 direction), the knob member 27 of the operating lever 23 moves in a direction away from the gripping portion 21a. Will do. Since the protruding portion 29 of the knob member 27 protrudes to one end side of the housing 21, the knob member 27 and the gripping portion are in a state where the lever body 25 of the operation lever 23 is inclined to the other end side of the housing 21. The distance from 21a can be reduced. Therefore, it is possible to prevent the finger F that operates the operation lever 23 from being extended in this state.

次に、操作レバー２３及び湾曲装置３０によって湾曲部１３を湾曲させる動作について図２を参照して以下に説明する。
はじめに、湾曲用モータ４１を駆動して軸部材３９を回転させておく。ここで、操作レバー２３が直立状態で保持されている場合には、全ての操作ワイヤ３５が所定の釣合い状態になって、全てのプーリー３７が軸部材３９に対して滑り状態になる。このとき、湾曲部１３は直線状態に保持される。
この状態から、例えば、湾曲部１３を上方向に湾曲動作させるために操作レバー２３のレバー本体２５を矢印Ｙ１方向に傾斜させた場合には、この操作レバー２３の移動と共にアーム部材３１が同じ方向に傾いていく。この際には、レバー本体２５の傾斜方向に対応するアーム部３１ａに固定された上方向用の操作ワイヤ３５が徐々に引っ張られた状態に変化していく。このとき、前記上方向とは逆の下方向に対応する操作ワイヤ３５は次第に弛んだ状態になっていく。 Next, an operation of bending the bending portion 13 by the operation lever 23 and the bending device 30 will be described below with reference to FIG.
First, the bending motor 41 is driven to rotate the shaft member 39. Here, when the operation lever 23 is held in an upright state, all the operation wires 35 are in a predetermined balance state, and all the pulleys 37 are in a sliding state with respect to the shaft member 39. At this time, the bending portion 13 is held in a straight state.
From this state, for example, when the lever main body 25 of the operation lever 23 is tilted in the arrow Y1 direction in order to cause the bending portion 13 to bend upward, the arm member 31 moves in the same direction as the operation lever 23 moves. It leans toward. At this time, the upward operation wire 35 fixed to the arm portion 31a corresponding to the inclination direction of the lever main body 25 is gradually pulled. At this time, the operation wire 35 corresponding to the downward direction opposite to the upward direction is gradually loosened.

そして、上述した操作レバー２３の移動に基づく操作ワイヤ３５の引張力が所定の大きさ以上となった場合には、プーリー３７が軸部材３９に一体的に固定され、軸部材３９の回転がプーリー３７及び操作ワイヤ３５に伝達される。したがって、挿入部３側に位置する操作ワイヤ３５が湾曲用モータ４１の駆動力によって瞬時に引っ張られ、湾曲部１３が上方向に湾曲することになる。すなわち、湾曲用モータ４１の駆動力を利用して湾曲部１３を湾曲させているため、小さな力で操作レバー２３を操作して湾曲部１３の湾曲を行うことができる。なお、レバー本体２５を同じ傾斜角度を維持し続けた場合には、湾曲部１３の湾曲状態が保持されることになる。   When the pulling force of the operation wire 35 based on the movement of the operation lever 23 described above becomes a predetermined magnitude or more, the pulley 37 is integrally fixed to the shaft member 39, and the rotation of the shaft member 39 causes the pulley to rotate. 37 and the operation wire 35. Therefore, the operation wire 35 located on the insertion portion 3 side is instantaneously pulled by the driving force of the bending motor 41, and the bending portion 13 is bent upward. That is, since the bending portion 13 is bent using the driving force of the bending motor 41, the bending portion 13 can be bent by operating the operation lever 23 with a small force. If the lever body 25 is kept at the same inclination angle, the bending state of the bending portion 13 is maintained.

その後、レバー本体２５をさらに矢印Ｙ１方向に傾斜させた場合には、湾曲部１３がさらに上方向に湾曲することになる。最後に、この状態から、操作レバー２３を直立位置に戻した場合には、操作ワイヤ３５が弛んで操作ワイヤ３５によるプーリー３７の締め付けが解除されると共に、プーリー３７が軸部材３９に対して滑り状態となり、湾曲部１３が直線状態に戻ることになる。   Thereafter, when the lever body 25 is further tilted in the direction of the arrow Y1, the bending portion 13 is further bent upward. Finally, when the operation lever 23 is returned to the upright position from this state, the operation wire 35 is loosened and the pulley 37 is not tightened by the operation wire 35, and the pulley 37 is slid with respect to the shaft member 39. It will be in a state and the bending part 13 will return to a linear state.

なお、ここではレバー本体２５を矢印Ｙ１方向に傾斜させてアーム部材３１のアーム部３１ａに固定されている上方向の操作ワイヤ３５を牽引移動させて湾曲部１３を湾曲させる操作例についてのみ説明したが、操作レバー２３を矢印Ｙ２方向或いは矢印Ｘ１方向、矢印Ｘ２方向に傾斜させることによって、上述と同様にレバー本体２５の傾斜方向に対応する操作ワイヤ３５を牽引して湾曲部１３を所望の方向に湾曲させる操作を行える。また、レバー本体２５を例えば矢印Ｙ２方向と矢印Ｘ２方向との中間方向等に傾斜させた場合には、上述と同様に傾斜方向に対応する複数の操作ワイヤ３５を対応する方向に移動させて湾曲部１３を所望の方向に湾曲させる操作を行える。   Here, only the operation example in which the lever main body 25 is inclined in the direction of the arrow Y1 and the upward operation wire 35 fixed to the arm portion 31a of the arm member 31 is pulled to bend the bending portion 13 has been described. However, by tilting the operating lever 23 in the arrow Y2 direction, the arrow X1 direction, or the arrow X2 direction, the operating wire 35 corresponding to the tilting direction of the lever body 25 is pulled in the same way as described above to pull the bending portion 13 in the desired direction. Can be bent. Further, when the lever main body 25 is tilted, for example, in an intermediate direction between the arrow Y2 direction and the arrow X2 direction, the plurality of operation wires 35 corresponding to the tilt direction are moved in the corresponding direction as described above to bend. An operation of bending the portion 13 in a desired direction can be performed.

上記のように、本実施形態の内視鏡システム１を構成する操作部５によれば、把持部２１ａを掴む手指Ｆにより操作レバー２３のレバー本体２５を把持部２１ａから離間する方向に傾斜させても、把持部２１ａを掴む手指Ｆを突出部２９に接触させておくことにより、手指Ｆが伸びきることを防止できるため、把持部２１ａを掴む手による操作レバー２３の操作性を向上できる。   As described above, according to the operation unit 5 constituting the endoscope system 1 of the present embodiment, the lever body 25 of the operation lever 23 is inclined in the direction away from the gripping part 21a by the finger F gripping the gripping part 21a. However, since the finger F can be prevented from extending by making the finger F gripping the gripping portion 21a contact the protruding portion 29, the operability of the operation lever 23 by the hand gripping the gripping portion 21a can be improved.

また、突出部２９をノブ部材２７と一体的に形成することにより、操作レバー２３を構成する部品点数を増やすことなく、操作レバー２３の操作性を向上できるため、操作部５の製造コスト増加を抑えることができる。
さらに、ノブ部材２７をレバー本体２５に対して着脱できるため、ノブ部材２７に接触させる手指Ｆの長さに応じて、突出部２９の突出長さが異なるノブ部材２７を選択することができる。すなわち、例えば、ノブ部材２７に接触させる手指Ｆの長さが短い場合には、突出部２９の突出長さが長いノブ部材２７を選択し、同手指Ｆの長さが長い場合には、突出部２９の突出長さが短いノブ部材２７を選択すればよい。 Further, by forming the protruding portion 29 integrally with the knob member 27, the operability of the operating lever 23 can be improved without increasing the number of parts constituting the operating lever 23, so that the manufacturing cost of the operating portion 5 is increased. Can be suppressed.
Furthermore, since the knob member 27 can be attached to and detached from the lever main body 25, the knob member 27 having a different protruding length of the protruding portion 29 can be selected in accordance with the length of the finger F brought into contact with the knob member 27. That is, for example, when the length of the finger F to be brought into contact with the knob member 27 is short, the knob member 27 having a long protruding portion 29 is selected, and when the length of the finger F is long, the protruding portion 29 protrudes. The knob member 27 having a short protrusion length of the portion 29 may be selected.

また、本実施形態の内視鏡システム１によれば、ＣＣＤにより撮像された画像を表示部の画面に表示して、この表示部の画面に操作レバー２３の傾斜方向を連動させることができるため、表示部の画面を見ながら直感的に操作レバー２３を操作することが可能となる。すなわち、例えば、画面の上側の領域を視認したい場合には、操作レバー２３を上側に傾斜させればよい。したがって、構造物の管内や隙間等の観察検査を容易に行うことができる。   Further, according to the endoscope system 1 of the present embodiment, an image captured by the CCD can be displayed on the screen of the display unit, and the tilt direction of the operation lever 23 can be linked to the screen of the display unit. The operation lever 23 can be intuitively operated while viewing the screen of the display unit. That is, for example, when it is desired to visually recognize the upper area of the screen, the operation lever 23 may be tilted upward. Therefore, it is possible to easily carry out observation inspection of the inside of the structure and the gap.

なお、上記の実施形態においては、突出部２９がノブ部材２７に一体的に形成されるとしたが、これに限ることはなく、例えば、突出部がノブ部材２７に対して着脱自在に設けられるとしても構わない。
この構成の場合には、把持部２１ａを掴む手指Ｆの長さに応じた適切な突出長さの突出部を選択してノブ部材２７に取り付けることができる。また、突出部のみを交換する構成であるため、ノブ部材２７自体の交換が不要となり、操作部５の製造コスト増加を抑えることができる。 In the above embodiment, the protrusion 29 is formed integrally with the knob member 27. However, the present invention is not limited to this. For example, the protrusion is detachable from the knob member 27. It does not matter.
In the case of this configuration, a protrusion having an appropriate protrusion length corresponding to the length of the finger F that holds the grip 21 a can be selected and attached to the knob member 27. Further, since only the protruding portion is replaced, it is not necessary to replace the knob member 27 itself, and an increase in manufacturing cost of the operation portion 5 can be suppressed.

また、延出手段は、ノブ部材２７から筐体２１の一端側に向けて突出する突出部２９からなるとしたが、これに限ることはなく、少なくとも操作レバー２３の先端を筐体２１の一端側に延出させる構成であればよい。すなわち、延出手段は、例えば、図４に示すように、レバー本体２６の中途部を筐体２１の一端側に向けて折り曲げた屈曲部２６ａから構成されるとしても構わない。
この構成の場合には、レバー本体２６を操作する手指Ｆに接触させるノブ部材２８が把持部２１ａ側に近づくことになる。したがって、操作レバー２４のレバー本体２６を筐体２１の他端側（Ｙ１方向）に傾斜させても、把持部２１ａを掴む手指Ｆをノブ部材２８に容易に接触させることできるため、手指Ｆが伸びきることを防止でき、把持部２１ａを掴む手による操作レバー２４の操作性を向上できる。 In addition, the extending means includes the protruding portion 29 that protrudes from the knob member 27 toward one end side of the housing 21, but is not limited thereto, and at least the tip of the operation lever 23 is at one end side of the housing 21. Any configuration may be used as long as it extends. In other words, the extending means may be constituted by a bent portion 26 a in which a middle portion of the lever main body 26 is bent toward one end side of the housing 21 as shown in FIG. 4, for example.
In the case of this configuration, the knob member 28 that is brought into contact with the finger F that operates the lever main body 26 approaches the grip portion 21a side. Therefore, even if the lever main body 26 of the operation lever 24 is inclined toward the other end side (Y1 direction) of the housing 21, the finger F that grips the grip portion 21a can be easily brought into contact with the knob member 28. It can be prevented from extending and the operability of the operation lever 24 by the hand holding the grip portion 21a can be improved.

上述した操作部５の構成は、工業用の内視鏡に適用されるとしたが、これに限ることはなく、体腔内の観察検査に使用する医療用の内視鏡に適用されるとしても構わない。
以上、本発明の実施形態について図面を参照して詳述したが、具体的な構成はこの実施形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計変更等も含まれる。 The configuration of the operation unit 5 described above is applied to an industrial endoscope. However, the configuration is not limited thereto, and may be applied to a medical endoscope used for observation inspection in a body cavity. I do not care.
As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
